Caption = Internal view of right inguinal area.

Inguinal triangle is not labeled, but can be seen at center left, by tracing out the margins of the three surrounding structures:
"inferior epigastric vessels": Run from upper left to center.
"inguinal ligament": Runs from upper right to bottom left.
"rectus abdominis muscle": Runs from upper left to bottom left, labeled "rectus" at upper left.



Caption2 = External view.

Inguinal triangle is not labeled, but region can be inferred, albeit less clearly than with the diagram above:
"inferior epigastric artery and vein": labeled at center left, and run from upper right to bottom center.
"inguinal ligament": not labeled on diagram, but runs a similar path to the inguinal aponeurotic falx, labeled at bottom.
"rectus abdominis muscle": runs from upper left to bottom left.
